Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625710, here are decompositions:

29 + 31625681 = 31625710
59 + 31625651 = 31625710
107 + 31625603 = 31625710
131 + 31625579 = 31625710
173 + 31625537 = 31625710
257 + 31625453 = 31625710
317 + 31625393 = 31625710
359 + 31625351 = 31625710

Showing the first eight; more decompositions exist.
